Hi Jenny!

You have to insert something like that into your W-B-P-trigger:

DECLARE

in_file		TEXT_IO.FILE_TYPE;
f_eof		boolean:=FALSE;
linebuf		VARCHAR2(1024):=NULL;
BEGIN
	:block.multiline_textfield:=NULL;
	in_file := TEXT_IO.FOPEN('/home/usr/file.txt','r');
	LOOP
		BEGIN
			TEXT_IO.GET_LINE(in_file, linebuf);
			f_eof:=FALSE;
		EXCEPTION
			WHEN others THEN
				f_eof:=TRUE;
		END;
		exit when f_eof;
		:block.multiline_textfield:=:block.multiline_textfield||CHR(10)||linebuf;
	END LOOP;
	TEXT_IO.FCLOSE(in_file);

END; aloha
